AndrewD,

thanks for the firebug tip, i never knew such a great tool existed. i've been able to find the problem with button, it appears that there's a line containing relative path to the actual flash object in links_swfuploader_header_one template and somehow this line was set to "/forum/clientscript/swfupload/swfupload.swf". i adjusted it for my setup and flash object begun working but there's a new problem now, after pressing submit button the local_links_actions.php just gives out blank screen. there's nothing in error_log and it appears that the problem may be somehow linked to file size: it successfully added 14kb gif but choked after uploading 0.5mb and 5mb jpegs.
